Antenna Alignment Procedure
4. Point the antenna
1
of the Master ODU in the general direction of the Slave ODU,
and secure it to the pole or wall.
5. From the Slave ODU, make a horizontal sweep of 180 degrees with its antenna so
that the strongest signal from the Master ODU can be detected.
6. Slowly turn the Slave ODU antenna back towards the position of the Master ODU,
listening to the tone until the best signal is reached. See the following figure for
audible signal variations.
Figure 4 ‐ 57: Beep Sequence for antenna alignment
• Three beeps and a pause is 'best signal so far'
• Two beeps and a pause is 'signal quality increased'
• One beep and short pause is 'no change in signal'
• Long beep and short pause is 'signal quality decreased'
• One beep and a long pause is 'no air link'
• Any other signal does not relate to antenna alignment
7. Secure the Slave ODU antenna to the pole/wall.
8. Repeat the above steps from the Master ODU, listening to its buzzer: make a
horizontal sweep of 180 degrees with its antenna so that the strongest signal from
the Slave ODU can be detected.
9. Slowly turn the Master ODU antenna back towards the position of the Slave ODU,
listening to the tone until the best signal is reached.
10. Secure the Master ODU antenna to the pole/wall.
11. Turn off the buzzer of the radio units from the RADWIN Manager (see Link
Configuration Tool Bar on page 7 ‐ 27 ).
1. If your unit has an integrated antenna, “pointing the antenna” consists of pointing the unit itself.
